I recently moved and had to destroy my previous scape. I have a rather large piece of Corbo wood which I would like to use as a focal point for a new low-tech and epiphytes-only scape. I was thinking an island style layout. I have contemplated about how to complete my hardscape but I just cannot make up my mind on the type and quantity for the rocks. I am leaning towards stackable porous rocks, either black lava rock or black star lava rock. I also have a 2nd smaller Corbo piece which I could also use. I would appreciate any ideas on how to proceed.
